Paperboard righting device of splitting machine

The utility model relates to the technical field of cutting equipment, in particular to a paperboard righting device of a splitting machine. A paperboard righting device of a splitting machine comprises the splitting machine used for splitting a paperboard into a plurality of blocks; the bearing table is arranged on the side, where the slitting machine outputs the slit paperboards, of the slitting machine and used for storing the paperboards which are slit into a plurality of blocks, and the bearing table comprises a bearing plate; and the at least two discharging mechanisms are arranged on the bearing plate side by side and can linearly move in the direction away from the splitting machine. The paperboard feeding device has the beneficial effects that the device can be used for automatically feeding cut paperboards, and also can be used for preventing the stacked paperboards after feeding from being placed in an inclined way due to disorder in the feeding process, so that when the stacked paperboards are pac
